Migrating Volumes in an XP24000 Disk ArrayDisk ProcessorDisk AdapterCluster

Migrate volumes from parity groups with the following

IDs to another parity group:

10-X

18-X

DKPF4-2WL

DKPF5-2WL

DKPF6-2WL

DKPF7-2WL

DKA-2WL2

NOTE:

The letter X is a placeholder for numerical values. For example, parity group 1-X indicates parity

groups such as 1-1 and 1-2.

XP Auto LUN cannot estimate DKP usage, and may not provide any performance improvement for

cases in which DKP usage values vary only slightly, or for cases in which overall DRR usage values

are relatively high. XP Auto LUN is designed for use with obvious cases of high or unbalanced DKP

usage. For more information on using XP Auto LUN, see the HP StorageWorks XP24000/XP20000

Auto LUN Software User Guide.

DRR Processor Usage Statistics

A data recovery and reconstruction processor (DRR) is a microprocessor (located on the DKAs) that

is used to generate parity data for RAID-5 or RAID-6 parity groups. The DRR uses the formula old data

+ new data + old parity to generate new parity.

If the monitor data shows high DRR usage overall, this can indicate high write penalty condition.

Please consult your HP representative about high write penalty conditions. If the monitor data shows

that DRR usage is not balanced, you should consider relocating volumes using XP Auto LUN to balance

DRR usage within the storage system.

For more information on using XP Auto LUN, see the HP StorageWorks XP24000/XP20000 Auto

LUN Software User Guide.

For details on how to view usage statistics on DRRs, see “Viewing Usage Statistics about Data Recovery

and Reconstruction Processors (DRRs)” on page 71.

Write Pending Rate and Cache Memory Usage Statistics

The write pending rate indicates the ratio of write-pending data to the cache memory capacity. The

Auto LUN window displays the average and the maximum write pending rate for the specified period

of time. When you display monitoring results in a short range, the window also displays the average

and the maximum usage statistics about the cache memory for the specified period of time. In addition,

the window can display a graph that indicates how the write pending rate or the usage statistics of

the cache memory changed within that period.

NOTE:

The data written to the Cache Residency cache area is not included in the write pending rate field.

For details on how to view the write pending rate and the usage statistics about the cache memory,

see “Viewing Write Pending and Cache Memory Usage Statistics” on page 72.
